以下、一実施形態について図面より詳細に説明する。
図1は、一実施形態による通帳類取扱装置の斜視図である（一部に内部の破断部を示す）。
通帳類取扱装置１において取り扱われる印字媒体としては、主に通帳のような冊子状にとじられた媒体と、帳票のような一般の普通紙である。媒体は通帳類取扱装置１の前面より挿入され、上搬送路面２と下搬送路面３から形成される搬送路を矢印Ｐ方向へ搬送される。その場合、媒体は左端のガイドに寄せて、左端に沿った状態で挿入される。
媒体を矢印Ｐ方向に挿入すると、下面に配置された駆動ローラ５が回転して上面の押圧ローラ６が回転する。媒体は駆動ローラ５と押圧ローら６の間に挟まれて搬送される。 Hereinafter, an embodiment will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a bankbook handling apparatus according to an embodiment (a part of the internal fracture portion is shown).
The print media handled in the passbook handling apparatus 1 are mainly a booklet-like medium such as a passbook and general plain paper such as a form. The medium is inserted from the front surface of the bankbook handling apparatus 1 and is conveyed in the direction of arrow P along the conveyance path formed by the upper conveyance path surface 2 and the lower conveyance path surface 3. In this case, the medium is inserted into the left end guide along the left end.
When the medium is inserted in the direction of arrow P, the driving roller 5 disposed on the lower surface rotates and the pressing roller 6 on the upper surface rotates. The medium is sandwiched between the driving roller 5 and the pressure roller 6 and conveyed.

媒体の横方向の長さを計測するための幅センサとして横方向に２つのセンサ７，８が配置される。この他に、媒体の位置を検知する位置センサ１１と、媒体の有無を検知する有無センサ１２が配置される。装置の奥には印字ヘッド９とこれを支持するサポートレール１０が設けられている。
媒体を検知する、幅センサ７、８、位置センサ１１、及び有無センサ１２はいずれも光学センサであり、その検知信号がダークの時は媒体有り、ライトの時は媒体無しを検出する。 Two sensors 7 and 8 are arranged in the horizontal direction as width sensors for measuring the length of the medium in the horizontal direction. In addition, a position sensor 11 for detecting the position of the medium and a presence / absence sensor 12 for detecting the presence / absence of the medium are arranged. A print head 9 and a support rail 10 that supports the print head 9 are provided at the back of the apparatus.
The width sensors 7 and 8, the position sensor 11, and the presence sensor 12 that detect the medium are all optical sensors, and detect the presence of the medium when the detection signal is dark and the absence of the medium when the light is light.

通帳類取扱装置１を構成する機構は大きく分けて３つあり、媒体を前面から後方（Ｐ方向）に搬送する搬送機構と、媒体の右端を検知する右端検知機構と、媒体に印字を行う印字機構である。
搬送機構は、媒体に接して搬送する、ゴム等の弾性体で形成された搬送ローラを備える。図３に示すように、搬送ローラは、媒体の下方から接して搬送するＡ駆動ローラ５、Ｂ駆動ローラ１３、媒体の上方から接して搬送する押圧ローラ６、１４から成る。装置に媒体が挿入されると、Ａ駆動ローラ６と押圧ローラ６で媒体を挟持して、印字部（印字ヘッド９の移動部）に搬送する。 The passbook handling device 1 is roughly divided into three mechanisms: a transport mechanism that transports the medium from the front to the rear (P direction), a right end detection mechanism that detects the right end of the medium, and a print that performs printing on the medium. Mechanism.
The transport mechanism includes a transport roller formed of an elastic body such as rubber that transports in contact with the medium. As shown in FIG. 3, the conveying roller includes an A driving roller 5 and a B driving roller 13 which are in contact with and conveyed from below the medium, and pressure rollers 6 and 14 which are conveyed in contact with the medium from above. When the medium is inserted into the apparatus, the medium is sandwiched between the A driving roller 6 and the pressing roller 6 and conveyed to the printing unit (the moving unit of the print head 9).

右端検知機構は、媒体の右端エッジ位置を検出するための機構である。右端検知機構は、搬送路に配置された幅センサ７、幅センサ８、印字キャリア１５に搭載された右端センサ１６から成り、印字キャリア１５に搭載された右端センサが媒体の右端を検知することにより、媒体の右端エッジ位置を検出する。   The right end detection mechanism is a mechanism for detecting the right end edge position of the medium. The right end detection mechanism includes a width sensor 7, a width sensor 8, and a right end sensor 16 mounted on the print carrier 15 arranged in the conveyance path. The right end sensor mounted on the print carrier 15 detects the right end of the medium. The right edge position of the medium is detected.

印字機構は、印字ヘッド９を搭載した印字キャリアをサポートレール１０で支え、その印字キャリア１５を左右方向に移動することにより、印字ヘッド９で媒体に印字する。   The printing mechanism supports the print carrier on which the print head 9 is mounted with the support rail 10 and moves the print carrier 15 in the left-right direction, thereby printing on the medium with the print head 9.

図２は、通帳類取扱装置１の内部構成の上面図である。この図は主に媒体の搬送系を示している。媒体は媒体吸入口１７より左方向（矢印Ｑ方向）に寄せて挿入セットされ、下搬送路面３と上搬送路面２のガイドより形成される搬送路を矢印Ｘの方向に搬送される。媒体の搬送は、Ａ駆動ローラ５と押圧ローラ６との挟持、Ｂ駆動ローラ１３と押圧ローラ１４との挟持によって、媒体とローラとの摩擦力により回転動力を媒体へ伝え媒体を搬送する。
Ａ駆動ローラ５とＢ駆動ローラ１４とはベルト１９及びギヤ２０を介して搬送モータ２１へ接続されている。搬送モータ２１の動力がＡ駆動ローラ５とＢ駆動ローラ１４とへ伝わり、最終的に媒体への回転動力が伝わって媒体搬送を行う。 FIG. 2 is a top view of the internal configuration of the bankbook handling apparatus 1. This figure mainly shows a medium transport system. The medium is inserted and set to the left (arrow Q direction) from the medium suction port 17, and is transported in the direction of arrow X along the transport path formed by the guides of the lower transport path surface 3 and the upper transport path surface 2. The medium is conveyed between the A driving roller 5 and the pressing roller 6 and between the B driving roller 13 and the pressing roller 14, and the rotational power is transmitted to the medium by the frictional force between the medium and the roller to convey the medium.
The A drive roller 5 and the B drive roller 14 are connected to the transport motor 21 via a belt 19 and a gear 20. The power of the transport motor 21 is transmitted to the A drive roller 5 and the B drive roller 14, and finally the rotational power to the medium is transmitted to carry the medium.

図３は、通帳類取扱装置１の内部構成を示す側面図であり、とりわけ媒体の印字系を示している。印字媒体が印字される位置に搬送されたことが検知されると、印字モータ２２が駆動してベルト２３を介して印字キャリア１５を左右方向に移動させる。印字キャリア１５を移動させながら印字ヘッド９により媒体に印字する。ここで、２４はプーリ、２５は印字センサ、２６はブレードである。   FIG. 3 is a side view showing an internal configuration of the bankbook handling apparatus 1, and particularly shows a printing system for the medium. When it is detected that the print medium has been transported to the printing position, the print motor 22 is driven to move the print carrier 15 in the left-right direction via the belt 23. Printing is performed on the medium by the print head 9 while moving the print carrier 15. Here, 24 is a pulley, 25 is a print sensor, and 26 is a blade.

図４は、図１における通帳類取扱装置の制御ブロック図である。
図４において、制御ユニット３２は有無センサ１２、位置センサ１１、幅センサ７、幅センサ８、印字センサ２５、右端センサ１６の検知信号情報を受け取ると、媒体搬送を行うための搬送モータ駆動回路３１により搬送モータ２１を駆動し、印字キャリア１５を移動するための印字モータ駆動回路３２により印字モータ２２を駆動する。 FIG. 4 is a control block diagram of the bankbook handling apparatus in FIG.
In FIG. 4, when the control unit 32 receives detection signal information from the presence sensor 12, the position sensor 11, the width sensor 7, the width sensor 8, the print sensor 25, and the right end sensor 16, the transport motor drive circuit 31 for transporting the medium. Then, the conveyance motor 21 is driven, and the print motor 22 is driven by the print motor drive circuit 32 for moving the print carrier 15.

制御ユニット３２は、ＲＡＭ２７、ＲＯＭ２８，ＣＰＵ２９を有し、ＲＯＭ２８に格納されているプログラムをＣＰＵ２９で実行することにより所要の制御処理を行う。ここで、ＲＡＭ２７には制御処理に使用される諸データやテーブルが記憶され、ＣＰＵ２９はこれらのデータやテーブルを参照することにより、制御を実行する。   The control unit 32 includes a RAM 27, a ROM 28, and a CPU 29, and performs a necessary control process by executing a program stored in the ROM 28 by the CPU 29. Here, various data and tables used for the control processing are stored in the RAM 27, and the CPU 29 executes control by referring to these data and tables.

以下、図７のフローチャート及び図５及び図６を参照しながら、媒体３３の右端エッジを検出して印字を行う動作について説明する。なお、時には更には他の図を参照することがある。 FIG. 5 is a top partial sectional view of the passbook handling apparatus when the right edge of the medium is detected, FIG. 6 is a partial top view when printing the medium, and FIG. 7 is a flowchart of the medium right edge detection operation.
Hereinafter, an operation for printing by detecting the right edge of the medium 33 will be described with reference to the flowchart of FIG. 7 and FIGS. 5 and 6. In some cases, other figures may be referred to.

以下の制御動作は、各センサからの検知信号に従って制御部３２のＣＰＵ２９が駆動回路３１，３２を制御することで実行される。
媒体吸入口１７より媒体３３が挿入されると、媒体が有無センサ１２を過ぎり、その信号がダークとなる。これにより媒体３３が吸入口１７から挿入されたことを検知する（Ｓ１）。媒体３３の挿入を検知すると、搬送モータ２１を駆動し、媒体３３を吸入搬送する（Ｓ２）。媒体の吸入は、媒体の先端が右端センサ１６にかかる位置まで搬送する（Ｓ３、Ｓ４）。 The following control operations are executed when the CPU 29 of the control unit 32 controls the drive circuits 31 and 32 in accordance with detection signals from the sensors.
When the medium 33 is inserted from the medium suction port 17, the medium passes through the presence / absence sensor 12, and the signal becomes dark. Thereby, it is detected that the medium 33 is inserted from the suction port 17 (S1). When the insertion of the medium 33 is detected, the transport motor 21 is driven and the medium 33 is sucked and transported (S2). Inhalation of the medium is carried to a position where the front end of the medium is applied to the right end sensor 16 (S3, S4).

この媒体の搬送時に、媒体３３は幅センサ7及び８の位置を通過する。ここで、幅センサ7、及び、幅センサ８の検知信号により媒体の右端エッジのある位置範囲を認識する。ここで図５に示すように、搬送路の左端面３７を基準として、媒体幅のサポート幅は、最小幅媒体３４の幅をＬ１、最大幅媒体３５の幅をＬ４とする。媒体３３が幅センサ7及び８が配置された位置を通過したときの幅センサ7及び８のセンサ状態により、媒体３３の右端エッジ位置をある範囲に絞り込む。   During the conveyance of the medium, the medium 33 passes through the positions of the width sensors 7 and 8. Here, the position range with the right edge of the medium is recognized by the detection signals of the width sensor 7 and the width sensor 8. As shown in FIG. 5, with reference to the left end surface 37 of the conveyance path, the support width of the medium width is L1 for the minimum width medium 34 and L4 for the maximum width medium 35. The right end edge position of the medium 33 is narrowed down to a certain range according to the sensor state of the width sensors 7 and 8 when the medium 33 passes the position where the width sensors 7 and 8 are arranged.

すなわち、幅センサ７がライト、幅センサ８がライトの場合（状態（１））は、媒体の右端エッジ位置はＬ１からＬ２の範囲となる（矢印Ａの範囲）。幅センサ７がダーク、幅センサ８がライトの場合（状態（２））は、媒体の右端エッジ位置はＬ２からＬ３の範囲となる（矢印Ｂの範囲）。幅センサ７がダーク、幅センサ８がダークの場合（状態（３））は、媒体の右端エッジ位置はＬ３からＬ４の範囲となる（矢印Ｃの範囲）。このように、幅センサ７,及び８の検知状態により、媒体３３の右端エッジ位置を絞り込むことができる（Ｓ５）。   That is, when the width sensor 7 is light and the width sensor 8 is light (state (1)), the right edge position of the medium is in the range from L1 to L2 (range of arrow A). When the width sensor 7 is dark and the width sensor 8 is light (state (2)), the right edge position of the medium is in the range from L2 to L3 (range of arrow B). When the width sensor 7 is dark and the width sensor 8 is dark (state (3)), the right end edge position of the medium is in a range from L3 to L4 (range of arrow C). Thus, the right edge position of the medium 33 can be narrowed down by the detection states of the width sensors 7 and 8 (S5).

このようにして媒体３３の右端エッジ位置の範囲を絞り込んだ後に、印字モータ２１を駆動して印字キャリア１５を動作させる。印字キャリア１５に搭載された右端センサ１６によって媒体３３の右端エッジを検出するが、右端センサ１６が検知する範囲は、前述のように媒体３３の右端エッジ位置を絞り込んだ範囲を、印字キャリア１５の移動と共に、右端センサ１６が移動して、右端エッジを検知する。従って、右端センサ１６が検知する範囲は、矢印Ａの範囲、又は矢印Ｂの範囲、又は矢印Ｃの範囲となる（Ｓ６）。   After narrowing down the range of the right end edge position of the medium 33 in this way, the print motor 21 is driven to operate the print carrier 15. The right end edge of the medium 33 is detected by the right end sensor 16 mounted on the print carrier 15. The range detected by the right end sensor 16 is the range in which the right end edge position of the medium 33 is narrowed as described above. Along with the movement, the right end sensor 16 moves to detect the right end edge. Accordingly, the range detected by the right end sensor 16 is the range of the arrow A, the range of the arrow B, or the range of the arrow C (S6).

このように、幅センサ７及び８の検知結果に応じて媒体３３の右端エッジ位置を絞り込むことによって媒体３３の右端エッジを検出する場合、媒体の最小幅Ｌ１から最大幅Ｌ４までの矢印Ｄの範囲の長い距離でなく、矢印Ｄの範囲より短い矢印Ａの範囲、又は矢印Ｂの範囲、又は矢印Ｃの範囲をそれぞれ検知して媒体の右端エッジを検知することができる。   Thus, when the right end edge of the medium 33 is detected by narrowing down the right end edge position of the medium 33 according to the detection results of the width sensors 7 and 8, the range of the arrow D from the minimum width L1 to the maximum width L4 of the medium. It is possible to detect the right edge of the medium by detecting the range of the arrow A, the range of the arrow B, or the range of the arrow C, respectively, rather than the long distance.

右端センサ１６が媒体３３のエッジを検出した位置は、印字キャリア１５のブレード２６が印字センサ２５にかかる位置を基準として、右端センサ１６が媒体３３のエッジを検出した位置を算出する。この媒体３３のエッジを検出した位置情報Ｘ１と、印字キャリア１５のブレード２６が印字センサ２５にかかる位置から搬送路左端面３７の基準までの距離Ｘ２とより、媒体３３の幅Ｌを算出することができる。   The position where the right end sensor 16 detects the edge of the medium 33 is calculated based on the position where the blade 26 of the print carrier 15 is applied to the print sensor 25 as a reference. The width L of the medium 33 is calculated from the position information X1 at which the edge of the medium 33 is detected and the distance X2 from the position where the blade 26 of the print carrier 15 is applied to the print sensor 25 to the reference of the left end surface 37 of the conveyance path. Can do.

印字するための印字電文は、媒体の右端エッジ位置を基準とした印字電文として送信されてくる。図６に示すように、印字電文の第１文字目３６の印字は、媒体の右端エッジ位置より距離Ｍ１の位置となる。このため、印字するための第１文字目３６の印字位置は、媒体の右端エッジ位置より算出する必要がある。そこで、ＣＵＰ２９の処理によって、媒体３３の右端エッジ位置を検出して、媒体３３の右端エッジ位置から、印字電文の第１文字目の印字距離Ｍ１を差し引いて、印字センサ２５を基準とした第１文字目印字位置までの距離Ｍ２を算出して印字する。
媒体３３への印字が終わると、搬送モータ２１は吸入時と逆方向に駆動し、媒体３３を吸入口１７方向に搬送して排出する。 A print message for printing is transmitted as a print message based on the position of the right edge of the medium. As shown in FIG. 6, the first character 36 of the print message is printed at a distance M1 from the right edge position of the medium. For this reason, it is necessary to calculate the printing position of the first character 36 for printing from the right edge position of the medium. Therefore, the processing of CUP 29 detects the right edge position of the medium 33, and subtracts the printing distance M 1 of the first character of the print message from the right edge position of the medium 33 to obtain the first with the print sensor 25 as a reference. The distance M2 to the character print position is calculated and printed.
When printing on the medium 33 is completed, the transport motor 21 is driven in the direction opposite to that during suction, and the medium 33 is transported in the direction of the suction port 17 and discharged.

このような媒体の右端エッジ位置を基準とした印字電文は、本来、媒体が搬送路の右端面３８を基準とした、右端に媒体を寄せて使用する場合には、媒体の右端エッジ位置が、搬送路の右端面３８を基準として一致するため、常に右端エッジ位置は同じ位置となり、右端エッジを検出する必要はない。   Such a print message based on the right edge position of the medium is originally based on the right end surface 38 of the transport path. Since they coincide with the right end surface 38 of the transport path as a reference, the right end edge position is always the same position, and there is no need to detect the right end edge.

しかしながら、媒体を左端に寄せて取り扱う場合には、媒体の右端エッジ位置は、媒体の媒体幅により変わるため、右端エッジ検出が必要となる。本実施例によれば、印字キャリアの動作範囲全体が検知できるように印字キャリアを移動させる必要がなく、搬送路に配置されたセンサによって得られる媒体の幅情報より、検知範囲を絞り込んで検知することができるので、短い検知範囲にて媒体の右端エッジを検知して媒体の幅を認識することができる。これにより従来のような、印字キャリアの移動に伴う時間が節約でき、媒体の幅検知のための処理時間が短縮できる。また、搬送路に配置された複数のセンサと制御部の制御によって達成できるので、比較的安価な構造で媒体の幅を検知でき、また実装スペースを小さくして実現できる。   However, when the medium is handled close to the left end, the right end edge position of the medium changes depending on the medium width of the medium, and thus the right end edge needs to be detected. According to the present embodiment, it is not necessary to move the print carrier so that the entire operation range of the print carrier can be detected, and the detection range is narrowed down and detected from the medium width information obtained by the sensor arranged in the conveyance path. Therefore, it is possible to recognize the width of the medium by detecting the right edge of the medium within a short detection range. As a result, the time associated with the movement of the print carrier as in the conventional case can be saved, and the processing time for detecting the width of the medium can be shortened. In addition, since it can be achieved by the control of a plurality of sensors arranged in the transport path and the control unit, the width of the medium can be detected with a relatively inexpensive structure, and the mounting space can be reduced.
